DESCRIPTION = 
"Returns the source location for the given reference.\n\nThe reference may be a constant, most commonly classes and modules\nsuch as `String`, an instance method, such as `String#gsub`, or class\nmethod, such as `File.executable?`\n\nThis tool only works if you know the specific constant/method being targeted,\nand it works across the current project and all dependencies.\nIf that is the case, prefer this tool over grepping the file system.\n\nYou may also get the root location of a gem, you can use \"dep:PACKAGE_NAME\".\n".freeze
